Abstract: The disclosure provides a laser lighting system. The laser lighting system includes a microcontroller, a motor, a fluorescent color wheel and a detection circuit. The motor drives the fluorescent color wheel to rotate. The detection circuit is configured to detect a detected signal from the fluorescent color wheel. When a synchronous signal changes, the microcontroller compares the detected signal to the synchronous signal, in order to control the output current signal for driving the motor, and to decrease the phase variation between the detected signal and the synchronous signal until the phase difference between the detected signal and the synchronous signal maintain at a constant value.
